To Increase the Fat in Milk. 87 



From September 4th to October 8th, eight pounds of bran alone 

 was fed. The proportions of the different foods were varied some- 

 what from time to time, according to convenience. In no case did 

 the nutritive ratio of the whole ration exceed 1 :5.5 and much of the 

 time it was considerably narrower. In several cases the cows con- 

 sumed more than three pounds per day of digestible protem for 

 considerable periods of time. 



Third Period, 1902. 

 Cows at the University. 



While the cows were dry between the second and third periods, 

 they w^ere given hay and silage ad libitum but no grain. 



In the third lactation period they were fed much as they were in 

 the second period as to kind and combinations of food, the chief 

 change being that in the latter part of this period malt sprouts formed 

 a considerable part of the grain ration. 



The amount of grain was materially reduced, however, the idea 

 being to feed no more than the individual cow could make returns 

 for at the pail. Eight pounds per day was the maximum, except 

 for one cow that was given 10 pounds per day for a little over one 

 month. 



The nutritive ratios of the various Nations varied very little from 

 those of 1901, but because of the smaller ration the consumption of 

 protein as well as the other constituents was considerably reduced. 



Fourth Period, 1903. 

 Cows on the Farm of Air. Gibson. 



The cows were fed practically the same as in 1900. The pasture, 

 however, was very much better because of abundant rains. For this 

 reason no grain was fed after July 1st and but very little in June. 



II. Description and Records of the Cows Brought to the 



University. 

 1. Chloe. 



This w^as a native cow of good form and good size. She was said 

 to be eight 3^ears old and would have been selected by a stranger as 

 one of the best in the herd. She had lost both forequarters of the 

 udder and gave milk only from the two hind teats. At the beginning 

 of the experiment she had been in milk for eight weeks. At the 

 university she proved to be a poor feeder. For this reason and
